The following statement are true about the given function

Statements i,ii, and iv

Given Data

We have the following function to analyse

y = 3x

The following statement are true/false about the given function

  • The function is a direct variation: this is true because an increase in the x value will increase the y value
  • The function goes through the origin:  for x = 0, y = 0
  • The constant of variation is 1/3: this statement is false, the constant of the variation is 3
  • y is 6, when x is 2: this statement is true, when we plug x = 3, the corresponding value for y is 6

HELP ASAP! The number of entertainment websites in 1995 wass 54. By 2004 there were 793 entertainment website..
AleksandrR [38]
<h3>Answer: Choice A. 82 websites per year</h3>

=============================================================

How I got that answer:

We have gone from 54 websites to 793 websites. This is a change of 793-54 = 739 new websites. This is over a timespan of 2004-1995 = 9 years.

Since we have 739 new websites over the course of 9 years, this means the rate of change is 739/9 = 82.1111... where the '1's go on forever. Rounding to the nearest whole number gets us roughly 82 websites a year.

----------

You could use the slope formula to get the job done. This is because the slope represents the rise over run

slope = rise/run

The rise is how much the number of websites have gone up or down. The run is the amount of time that has passed by. So slope = rise/run = 739/9 = 82.111...

In a more written out way, the steps would be

slope = rise/run

slope = (y2-y1)/(x2-x1)

slope = (793 - 54)/(2004 - 1995)

slope = 739/9

slope = 82.111....

Answer = $160

Using the formula 100+4n, we need to substitute 15 with n. Therefore making the formula, 100 + 4×15. 4×15 = 60. 60+100= $160.

A ; 1/2. B ; 1/3. C ; 2/3 D ; 4/9
hichkok12 [17]

Option B, 1/3

Since pepper topping can be in any size pizza, it remains as a 1/3 probability, since there are three toppings per size.
